Goliath is the third book in Scott Westerfeld's Leviathan trilogy. The stories follow an alternate steampunk history at the beginning of World War 2. On one sidw of the war are the Darwinists (England, France, Russia, and the US) who use Darwin's theory of evolution to create their own war-beasts and airships made out of the lifethreads of thousands of different organisms. Their machines are literally alive. On the other side are the Clankers (Germany, Austro-Hungary, etc.) who use machines made and guns made out of metal and gears that use oil and steampressure to move.

I see all these WWI Propaganda posters and I don’t' know what to do. I see all these posters talking about how I should join the war. On one hand I feel like I need to join the army because if I don’t join I will feel like I am not American. I love my country but I don't really want to fight. I see these posters and it seems like the country really needs me. I understand that I might have to fight even if I don’t want to, but I would at least like to know what I am fighting for. It seems s like the war is fought for something I don’t know. The posters keep saying that the country is in dire straights but the country is not really under attack.
